Description

If you've always wanted a bullpup airgun, this is the one you should get! The Benjamin Bulldog is shrouded. That means this pup has a big bite and a small bark!

Not only is it a repeater, but it's built with accessorizing in mind. You can put a flashlight, scope, bubble level and/or laser on your rifle and be ready for any situation that arises from dawn til dusk. In fact, any optical accessory made for the AR platform can be easily added to your Benjamin Bulldog.

Offered in .257, .357, and .457 calibers, the Bulldog Magnum Series offers multi-shot capability with easy follow up shots coming by way of a side lever action. If you're left-handed, don't forget to order our service to switch the side lever to the other side of the gun. Producing around 300 FPE in .357 and up to 450 FPE in .457, the Bulldog can take medium and large game ethically and effectively.

Using the .457 Bulldog with the Benjamin 279 grain flat nose slugs, from a 3000 PSI fill. Approximately 2200 PSI remaining after 3 shots:

Shot 1: 769 FPS
Shot 2: 747 FPS
Shot 3: 719 FPS

Tech Tip: Some of the longer and heavier slugs will not fit into the .457 magazine and need to be single loaded. In our experience, this includes most slugs that are 350 grains and heavier.

Very powerful and accurate

Foster fitting cover is very flimsy and cheaply made. They put a lot of effort into making this an exceptional rifle, but skip over this little detail.

It's definitely a slug gun. It will fire .25 pellets and slugs, but not very well. It is chambered and rifled for .257. Griffin slugs are exceptional in it.

A true powerhouse. The M257 definitely lives up to the hype. Packs a really good punch, and is very accurate. I am sure it will get even better with use and breaking in.

The protective foster fitting cap leaves much to be desired. Very cheap and flimsy. I believe they could do much better. For the price they have installed a regulator, but overall performance is good.

Don't expect to get good results with pellets. This a slug gun, and bored for .257, not .25. Although they will fire, they are not accurate at all.

Power, power, power. Not too heavy. Shoulders nice. Great pic rail. Easy to fill. Accurate out to 100 yards. Nice side lever.

The magazine has some slight issues with how it holds the ammo and cycles, but not too bad.

The gun is a beast and it's one of my favorites to shoot. A real powerhouse and accurate. High priced but ultimately worth it for hunting or blowing up water jugs or other targets. Quality is high priority at Benjamin for sure. Heavier ammo seems to shoot best. 140 grain slugs. 80 gran pellets work decent too, but the slugs seem to be the most accurate at distance.

The lever breaks easily. I've had to replace 2.

Great power, compact design, balances great for a bull pup.

The thread m-18x1 sucks too big 1/2x20 would be just fine for a LDC sized for 357 the gun is loud very loud so without a LDC herring pro is a must have

You better have a bottle to fill a fast shot of air on a new gun because my gun had two stuck valves one was the main hammer spring valve and the second was the check valve on the foster fitting

Easy to load and cock

Better air feel cover

Has plenty of power

whtdevl May 21, 2024

I sent my bulldog to Pitbull Air, added moderator and upgrades. I have a Leupold 3x9 40mm scope. With Griffin airgun ammo this gun will shoot 1 inch groups at 50 yds all day. Does not shoot the Noslers well, maybe 2 inch groups, they do not expand. No good for hunting.

Accurate huge power threaded barrel excepts ronnin donnyfl silencer

Shot tray is clumsy I prefer to single load need single shot tray. Needs scope risers

Buy a compressor!!!!

MegaPittbull purchase takes care of all worthwhile mods you can do to this weapon including suppression to 68db at the bench, 61db at 50 yards, and 54db at 100 yards. And it's equal to the newer Magnum in FPE. Get an AV 98cuft tank and its $7.00 at the dive shop to fill it to 4500 PSI. Lots of gun fills from that.

Big power accurate shot grouping

Riser for scope in package. Single shot tray would help with longer ammo

Objective Bell on scopes need to clear pica buy a riser or rings that are tall
